To install Capstone, you should run `pip install capstone`.
Python package building rework (#2538) * - Refactored setup.py to remove hacks regarding packaging of wheels for different platforms, improve and cleanup the code - Updated README.txt - Removed old Makefile and build_wheel.sh scripts - Created a new workflow that takes care of building and testing python packages for different platforms/architectures/python versions * Added SPDX headers to the setup.py * - cstest_py: Fixed positional argument since it doesn't accept a `required` flag. It turns to have a mandatory tests folder path - integration_tests.py: Use pathlib to determine the required path - GitHub action: Simplified the tests execution command * GitHub Actions: Run python 3.8 (lowest) and 3.13 (current highest) for native runners only during testings and the rest during tag release * GitHub Action: - Fixed the cibw_build matrix element - Added a step to prepare artifact name * GitHub Action: Added run_tests.py script to run all tests during CI workflow * - Added SPDX headers to the run_tests.py script and to the build-wheels-publish.yml workflow file - Minor fixes to the workflow as pointed out in the PR review - Updated MANIFEST.in to reflect the actual libraries built during python wheel creation process - Use subprocess.run in place of os.system in run_tests.py script * GitHub Action: - Run qemu step only if non-native Linux runner - Added arch:universal2 matrix element for macos-latest runner * Python bindings: Refreshed the list of files needed to be copied for sdist archive * GitHub Action: Commented out arch:x86 matrix elements * GitHub Action: Run qemu step only if non-native Linux runner * GitHub Action: Minor fixes * Python bindings: Added missing .in pattern when collecting src files for sdist archive

If you would like to build and install Capstone with just the source distribution,
just run `python -m pip install .`, considering you are in the folder with setup.py in it.
In order to use this source distribution, you will need an environment that can
compile C code. On Linux, this is usually easy, but on Windows, this involves
installing Visual Studio and using the "Developer Command Prompt" to perform the

installation. See BUILDING.md for more information.
By default, attempting to install the python bindings will trigger a build of
the capstone native core. If this is undesirable for whatever reason, for
instance, you already have a globally installed copy of libcapstone, you may
inhibit the build by setting the environment variable LIBCAPSTONE_PATH. The
exact value is not checked, just setting it will inhibit the build. During
execution, this variable may be set to the path of a directory containing a
specific version of libcapstone you would like to use.
If you don't want to build your own copy of Capstone, you can use a precompiled
binary distribution from PyPI. Saying `pip install capstone` should
automatically obtain an appropriate copy for your system. If it does not, please

Capstone is a disassembly framework with the target of becoming the ultimate
disasm engine for binary analysis and reversing in the security community.
Created by Nguyen Anh Quynh, then developed and maintained by a small community,

The cs_regname API can not pass the variant name of the register requested. So we simply emit the default variant name. * Fix incorrect enum value. * Fix tests for system operands. * Fix syntax issues in tests. * Rename Arm64 -> AArch64 Python bindings. * Fix Python bindings C structs. * Fix generation of constants (ARMCC skipped because it starts with ARM) * Update const files * Remove -Wmaybe-uninitialized warning since it fails fuzz build * Add missing comma * Fix case * Fix AArch64 Python bindings: - Do not generate constants automatically (dscript is way too buggy). - Update printing of details. * Rename ARM64 -> AArch64 in test_corpus.py * Rename test_arm64 -> test_aarch64 * Rename ARM-64 -> AArch64 * Fix diff CI test by disassembling AArch64 at former ARM64 place * Fix several wrong types and remove unnecessary memebers from Python binding * Fix: Same printing format of detail for cstool, test_ and test_*.py * Fix: pass correct op index for mov alias with op[1] == reg wzr. * Set prfm op manuall in case of unnown sysop. set_imm would add it to an memory operand wihtout base. * Fix: If barrier ops are not set an assert is reached. We fix it here by simply getting the immediate as the printing code does. --------- Co-authored-by: Peace-Maker <peace-maker@wcfan.de> Co-authored-by: Dayton <5340801+watbulb@users.noreply.github.com>
